Check Digit Verification of cas no

The CAS Registry Mumber 1512800-77-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,1,2,8,0 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1512800-77:
(9*1)+(8*5)+(7*1)+(6*2)+(5*8)+(4*0)+(3*0)+(2*7)+(1*7)=129
129 % 10 = 9
So 1512800-77-9 is a valid CAS Registry Number.

A chromogenic assay for limit dextrinase and pullulanase activity

B?jstrup, Marie,Christensen, Caspar Elo,Windahl, Michael Skovbo,Henriksen, Anette,Hindsgaul, Ole

, p. 45 - 51 (2014)

A new chromogenic substrate to assay the starch debranching enzymes limit dextrinase and pullulanase is described. The 2-chloro-4-nitrophenyl glycoside of a commercially available branched heptasaccharide (Glc-maltotriosyl- maltotriose) was found to be a suitable specific substrate for starch debranching enzymes and allows convenient assays of enzymatic activities in a format suited for high-throughput analysis. The kinetic parameters of these enzymes toward the synthesized substrate are determined, and the selectivity of the substrate in a complex cereal-based extract is established.
